Specification of Letters Patent.

Patented Jan. 22, 1507.

Application filed February 28, 1906. Serial No. 303,402.

To aZZ whom it may concern:

Be it known that I, GEORGE T. HUNNE- WELL, a citizen of the UnitedStates, residing at Great Falls, in the county of Cascade, State ofMontana, have invented certain new and useful Improvements inSwimming-Machines; and I do hereby declare the following to be a full,clear,.and exact description of the invention, such. as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to swimming appliances.

- One object is to provide a device for attachment to the foot of aswimmer to promote speed.

.Another object of the invention resides in the provision of anexceedingly simple, ineX pensive, durable, and efficient device of thecharacter stated wherein the swimmer will be aided in swimming exercisewithout undue discomfort.

With these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, pro portion, size, and minor details may be made within thescope of the clains without departing from the spirit or sacrificing anyof the advantages of the invention.

In the drawings, Figure 1 is an elevationof my invention. Fig. 2 is anend view. Fig. 3 is a detail sectional View. Fig. 4 is a longitudinalsectional view. Fig. 5 is a transverse sectional view. Fig. 6 is adetail view of one of the posts for the support of the keel.

Referring now more particularly to the accompanying drawings, thereference charaoter 1 des1gnates a foot member whose upper face 2 isdesigned to rest against the sole of the swimmers foot. The ends 3 and 4are beveled downwardly toward each other toward the bottom 4 of thefoot-piece 1. This bottom 4 is provided with a recess 5, whose sides arebeveled, as at 6, while the sides of the footpiece l'are also beveledinwardly and upwardly toward the upper face 2 thereof.

A rod 7 is arranged longitudinally of the recess 5 and is designed tosupport the wings 8 and 9 of any suitable material. It will be observedthat the wings 8 and 9 are formed of a single piece of material and thateach wing is oval in formation, the connecting portion 10 of the wingsbeing considerably nar rower than the length of the latter to correspondwith the lengthof the recess 5. These wings are formed of such materialas to permit their movement toward and away from each other according tothe movement of the foot of the swimmer.

The reference character 11 designates a keel member which is providedwith notches 12 and 13 near each end thereof for engagement in thevertical slits a of the corresponding posts 14 and 15, whose reducedends 16 are fitted in the corresponding recesses 17, disposed fore andaft of the aforesaid longitudinal recess 5. Formed in the rear of thetransverse recess 5 is a projecting lug 18, provided with. a slit 19,adapted for alinement with the said recesses and also with the grooves20 and 21, communicating, respectively, with the front and rear ends ofthe longitudinal recess 5 and also arran ed inalinement with the saidrecesses 17. t will be observed that this keel member has its upperedges adjacent the posts 14 and 15 beveled to fitcorrespondingly-beveled front and rear ends of the under face ofthefootpiece 1 with the rear upper edge of the keel member, also formedto engage in the slit 19 of the projecting lug 18; In other words, theupper edge of the keel member 11' is so formed as to fit in the groovesand recess of the under face of the foot-piece 1 and tightly against theremaining portions thereof. It will be seen, too, that the keel member11 is of greater length than the foot-post 1. In the use of the devicethe foot-piece is applied to the foot in any suitable manner, and0bviously by reason of movement of the swimmers footthe wings 8 and 9 ofthe appliances will move backwardly and forwardly, and thereby greatlyaid the swimmer with refer ence to speed.

\Vh at is claimed is .1. A device of the character described comprisinga foot-piece having a longitudinal recess in its under face, a rodmounted in the recess, wings mounted on the rod, and a keel membersecured to the under face of the footpiece and arranged between saidwings.

2. A device of the character described comprising a recess in its underface, a rod arranged in said recess, a pair of Wings constructed of asingle piece of material and supported upon said rod, forward and rear-Ward posts depending from the under face of the foot-piece at oppositeends of the said recess, and a keel member secured to said posts andextending between said In testimony whereof I affiX my signature 111presence of two v ltnesses.
